The tool used for checking the external diameter of a round bar is called a caliper, specifically a digital or dial caliper. These calipers can accurately measure the diameter by using their jaws to grasp the round bar at its widest point. Alternatively, a micrometer can also be used for more precise measurements, particularly for smaller diameters. Both tools are essential for ensuring that the round bar meets specified dimensions in manufacturing and engineering applications.

The most precise and accurate instrument for measuring diameter is typically a micrometer screw gauge. This tool allows for measurements with a high degree of precision, often to the thousandth of a millimeter. For larger diameters, a caliper, particularly a digital caliper, can also provide accurate measurements, but micrometers are generally favored for their finer resolution in smaller diameter measurements.
A caliper is a measuring tool that measures either the inside or outside diameter of something. Disc brakes on a car use a caliper to push the brake pads against the rotor to stop the car.

A micrometer is a common instrument used to measure the external and internal diameter of a test tube. It is a precision tool that provides accurate measurements of small distances. Another option is a caliper, which can also be used for measuring diameters.
Here is a url that shows how to make the guillotine tool - the tool that holds the fuller: http://www.britishblades.com/forums/showthread.php?78415-Guillotine-tool-quot-how-to-quot To make the fuller, simply round the ends of the two dies or weld a piece of round stock (the diameter of the die thickness) on to the die faces to make the fullers. Other adaptations can be made, limited only by your imagination.

To accurately measure the diameter of a screw, use a caliper or a micrometer. Place the screw between the jaws of the measuring tool and tighten it gently. Read the measurement displayed on the tool to determine the diameter of the screw.

A SWOT analysis is an internal assessment tool used to evaluate a company's strengths and weaknesses, as well as opportunities and threats in its external environment.
Depends on what you're checking. A piece of window glass works well for checking push rods for straightness. A machinists straight edge is good for checking heads and decks.
